Mbeans 与 JBoss

Question

我正在尝试调用部署在 JBoss 中的 MBean，但遇到此异常：

java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is:

我正在使用 JBoss 5.1.0GA，并且客户端代码是

    Properties env = new Properties();
            env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
            env.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
            env.put(Context.PROVIDER_URL, "jnp://localhost:1099");

            InitialContext ctx;
            ctx = new InitialContext(env);

            MBeanServerConnection server = (MBeanServerConnection)ctx.lookup("jmx/rmi/RMIAdaptor");


               // get reference to CacheMgmtInterceptor MBean

              String cache_service = "jboss:service=JNDIView";
               ObjectName mgmt_name = new ObjectName(cache_service);
               System.out.println( server.getMBeanInfo(mgmt_name).getClassName());
               Object[] obj = new String[1];
               obj[0]= new String("hello Sapo pepe");
            Object temp = server.invoke(mgmt_name, "sayHello", obj, new String[]{"String"});
            System.out.println(temp);

我可以访问抛出 JBOSS JNDI-Console，因此 MBean 正在工作。 提前致谢

好吧，问题是 Eclipse 执行客户端时类路径中没有 jboss 客户端 jar。

解决方案是在 Eclipse 的运行配置选项的类路径选项卡中添加 jar 文件。
